Perceptions of In-Service Teachers Regarding Technology Integrated English Language Teaching
Asl? Lidice G?ktürk Sa?lam,Semih Sert
Turkish Online Journal of Qualitative Inquiry , 2012,
Abstract: Technology is changing paradigms in education rapidly and teachers are caught unguarded due to lack of professional training in this aspect. This study reflects the perceptions of nine ELT instructors with M.A TEFL degrees and with over six years of professional experience. Despite the lack of formal professional training as part of their pre-service teacher education, these instructors need to cope with the demands of this transition in daily implementation. Data were collected through semi-structured interviews, open-ended questionnaires and field notes. An inductive analysis approach was used to analyze the data and emergent patterns of data were used to develop coding categories. Results indicated that respondents held positive views about the role of educational technology for enriching language instruction. However, they also acknowledged the challenges faced and emphasised the need for ICT training not only for teachers but also for students. It is concluded that participants make use of technology to teach academic and linguistic skills in an integrated skills approach, encourage students to construct knowledge, expose students to life-long learning skills and strategies, cater for different students who have different learning styles, find and create teaching materials, develop skills through exposure to existing on-line sources and create a motivating environment that is conducive for learning.
Matrix Operations Design Tool for FPGA and VLSI Systems  [PDF]
Semih Aslan, Jafar Saniie
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.72005
Abstract: Embedded systems used in real-time applications require low power, less area and high computation speed. For digital signal processing, image processing and communication applications, data are often received at a continuously high rate. The type of necessary arithmetic functions and matrix operations may vary greatly among different applications. The RTL-based design and verification of one or more of these functions could be time-consuming. Some High Level Synthesis tools reduce this design and verification time but may not be optimal or suitable for low power applications. The design tool proposed in this paper can improve the design time and reduce the verification process. The design tool offers a fast design and verification platform for important matrix operations. These operations range from simple addition to more complex matrix operations such as LU and QR factorizations. The proposed platform can improve design time by reducing verification cycle. This tool generates Verilog code and its testbench that can be realized in FPGA and VLSI systems. The designed system uses MATLAB-based verification and reporting.
Turkey’s Complex Place in the World: An Overview
Semih Idiz
Revista CIDOB d'Afers Internacionals , 2006,
Abstract: Without aiming to be an academic text, this article offers a journalistic “photograph” of the place which Turkey occupies in the world today. For this, it focuses firstly on this country’s relations with the United States. Then it reviews the bonds which link it toEurope: to the EU, in general, as well as to Spain, the United Kingdom, France, Germany, Austria and the new Member States, in particular. It also makes special mention of the Balkans, the Middle East, the Caucasus and Russia.
Tagging Accuracy Analysis on Part-of-Speech Taggers  [PDF]
Semih Yumusak, Erdogan Dogdu, Halife Kodaz
Journal of Computer and Communications (JCC) , 2014, DOI: 10.4236/jcc.2014.24021

Part of Speech (POS) Tagging can be applied by several tools and several programming languages. This work focuses on the Natural Language Toolkit (NLTK) library in the Python environment and the gold standard corpora installable. The corpora and tagging methods are analyzed and com- pared by using the Python language. Different taggers are analyzed according to their tagging ac- curacies with data from three different corpora. In this study, we have analyzed Brown, Penn Treebank and NPS Chat corpuses. The taggers we have used for the analysis are; default tagger, regex tagger, n-gram taggers. We have applied all taggers to these three corpuses, resultantly we have shown that whereas Unigram tagger does the best tagging in all corpora, the combination of taggers does better if it is correctly ordered. Additionally, we have seen that NPS Chat Corpus gives different accuracy results than the other two corpuses.

Open Source Synthesis and Verification Tool for Fixed-to-Floating and Floating-to-Fixed Points Conversions  [PDF]
Semih Aslan, Ekram Mohammad, Azim Hassan Salamy
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.711323
Abstract: An open source high level synthesis fixed-to-floating and floating-to-fixed conversion tool is presented for embedded design, communication systems, and signal processing applications. Many systems use a fixed point number system. Fixed point numbers often need to be converted to floating point numbers for higher accuracy, dynamic range, fixed-length transmission limitations or end user requirements. A similar conversion system is needed to convert floating point numbers to fixed point numbers due to the advantages that fixed point numbers offer when compared with floating point number systems, such as compact hardware, reduced verification time and design effort. The latest embedded and SoC designs use both number systems together to improve accuracy or reduce required hardware in the same design. The proposed open source design and verification tool converts fixed point numbers to floating point numbers, and floating point numbers to fixed point numbers using the IEEE-754 floating point number standard. This open source design tool generates HDL code and its test bench that can be implemented in FPGA and VLSI systems. The design can be compiled and simulated using open source Iverilog/GTKWave and verified using Octave. A high level synthesis tool and GUI are designed using C#. The proposed design tool can increase productivity by reducing the design and verification time, as well as reduce the development cost due to the open source nature of the design tool. The proposed design tool can be used as a standalone block generator or implemented into current designs to improve range, accuracy, and reduce the development cost. The generated design has been implemented on Xilinx FPGAs.
Annual Review of Education, Communication and Language Sciences , 2008,
Abstract: This paper, part of an ongoing study on the analysis of hyperboles in a British TV series, reports findings drawing upon a 90,000 word corpus. The findings are compared to the ones from CANCODE (McCarthy and Carter 2004), a five-million word corpus of spontaneous speech, in order to identify similarities between the two. The analysis showed that TV series can be a useful tool for EFL learners when accompanied by explicit instruction in order to enhance communicative competence, and can be used to teach hyperbolic lexical items specifically. A sample lesson plan is also given for practical use in classrooms.
A Comparative Analysis of Pair-work and Individual Assignments In two ELT Grammar Classes
Olcay Sert
Journal of Language and Linguistic Studies , 2005,
Abstract: Assignments prepared in pair-work have long been evaluated to be more successful whencompared to individually prepared assignments in many respects in foreign language learningcontexts. However, there is not much research conducted to reveal the advantages of pair-work in preparing assignments and the linguistic characteristics of the finished texts. In this paper, depending upon an experimental study with the first year students in Department of EnglishLanguage Teaching at Hacettepe University, quality of pair-work assignments and the factors affecting the preparation process are discussed and compared to individual assignments. Results indicate a variety of advantages of student collaboration in preparing written work since outputsare far more grammatical, include less spelling mistakes, and indicate a higher level ofgrammatical awareness. Additionally, pair-work helps students build positive interpersonalrelationships and create a high level of academic solidarity and confidence.

Journal of Theory and Practice in Education , 2008,
Abstract: The aim of this study was to examine whether the 5th grade elementary school curricula of Turkish, English, Mathematics, and Science and Technology courses were congruent with the principles and standards of the constructivist education. Qualitative research methods were used in this small-scale case study which was conducted in a private elementary school in Ankara. The data were gathered through semi-structured interviews and document analyses in the academic year of 2007-2008. The population of interest consisted of 2 school directors, 1 Turkish teacher, 3 English teachers, 4 Mathematics teachers, and 3 Science and Technology teachers. Descriptive analytical framework was employed for the analysis of the interviews. A rubric and a list of standards were used so as to provide a set of criteria for the analyses of the data. The findings indicate that the performances of the curricula under investigation are congruent with the principles of the constructivist education. Similarly, the stated and unstated intents of the curricula are congruent with their performances and the standards of the constructivist education. However, in-depth analyses of the findings signify that in certain areas of the curricula such as the contents, learning processes, evaluation processes, the use of the information technology, and the other resources are marked by some difficulties and ambiguity.

Physics , 2012, DOI: 10.1140/epjp/i2012-12152-5
Abstract: We investigate $ Y(R) F^2 $-type coupling of electromagnetic fields to gravity. After we derive field equations by a first order variational principle from the Lagrangian formulation of the non-minimally coupled theory, we look for static, spherically symmetric, magnetic monopole solutions. We point out that the solutions can provide possible geometries which may explain the flatness of the observed rotation curves of galaxies.
